Product Description

Black Aluminum Oxide for Metal surface cleaning abrasives media


Black Aluminum Oxide/Black fused alumina/Black Corundum is characterized by low Al2O3 and a certain amount of Fe2O3 (10% more or less) content, so Black corundum has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.what's more black fused alumina with the characteristics of strong cutting power, high toughness, high flexibility, good abrasion resistance and high working efficiency, It is the best product for grinding and polishing, sandblasting stainless steel products.
